Delay-dependent robust stabilizability of singular systems with delays

This paper deals with the class of continuous-time singular uncertain linear systems with time delay in the state vector. The uncertainties we are considering are of norm bounded type. Delay-dependent sufficient conditions on robust stability and robust stabilizability are developed. A design algorithm for a memoryless state feedback controller which guarantees that the closed-loop dynamics are regular, impulse free and robustly stable is proposed in terms of the solutions to linear matrix inequalities (LMIs).
